Hoping to purchase this car.. They ran a DME and this shows only 19 Over Revs in Range 1 with none across the other ranges.. there are a "high"? number of misfires? Is this a concern or perhaps normal and maybe just require plugs / coil packs? My 1st Porsche.. I hope...
My first post here so please bear with me but pretty desperate for help. Have 2004 Boxster S and its, in general, running a bit rough (feels fuel rich). It also will also, on occasion, not go. Pulling up at a busy intersection and car reduces to Idle. Then put the foot down and the car stays at idle. Normally an engine restart gets things going again (although not always and sometimes requires a few goes).
Bought a computer reader and found error codes
P0102: Factory Fault code 115 - Mass air flow sensor - below limit
P2135: Accelerator Pedal - Signal Implausible
P0121: Factor Fault code 117 - Throttle value or accelerator pedal potentiometer - signal implausible
P1266: Factory Fault Code 409 - Fuel shutoff function monitor - signal implausible
Took the car to Porsche. They suggest a MAF sensor was the root cause and replaced it. It felt better for a few days then problem returned. They replaced another MAF sensor.. Same problem. They then said the MAF reads 0 and have checked the cables so its me DME and it needs replacing (not cheap)
Have taken the car back home and looked at the likely affecting values myself from the computer.
The computer shows to different values for MAF
Mass air flow (HFM) is always 0 regardless of if the car is working correctly or not and at any accelerator level
Mass air flow seems to move within a range of 18 (idle) to 100 (full throttle)
2. Throttle (since it had error codes on this)
Pedal encoder potentiometer 1 and 2 always move and the pedal value goes from 0-100% when its working but stays at 0 when its not. Since the potentiometers always move I am assuming the DME simply can't add things up so sticks the pedal value at 0.
ie. The MAF sensor reading above confuses the DME and it reduces the throttle to 0. That feel consistent with the behaviour of the car (its just sticks at idle)
Any one with any clues? Certainly don't want to replace the DME unless absolutely necessary....
Hey guys - long time no see (which means 10+ years of bulletproof ownership!)
both my my keys fobs have given up the ghost
i am ok with manual locking but when I turn the key to lock from outside only the driver door locks
if I am inside the car and press the lock switch both doors lock
no beeps / no codes
im sure there's a way to program the car to lock and unlock both doors when I manually lock with the key
can someone point me in the right direction? Loren ?
Sometimes when programming the DME or Alarm control unit with the PST2 or PIWIS, you will get an error of "Test Step Aborted" followed by an error number, such as 3, 21, 25, 71 etc.
I have the PST2 manuals, as well as the KTS manuals and the 986 and 996 Dealer manuals, but one thing I have not been able to find in any of them is a list of error codes that follow the "test step is aborted message"
Sometimes, I have had the errors when I have put in an incorrect "old immobiiser code", or "old learning code", which kind of make sense.. But I often get the error when programming a control unit (yes I do have 14v onto the control unit and pin 60 powered up on the DME when it is a 5.2.2 DME)
Has anyone ever found a list of the error codes and what they mean, or even worked out what they mean?
When programming a DME 5.2.2 for example, I can often get to about 90 percent on the progress screen before it bombs out with one of these codes.
The unit will still start the car etc if it bombs out, so I don't think it is a bricked DME, but I am just curious about the meaning of the error codes
Anyone have any clues? or is my curiosity sending me towards a massive mission of discovery in an unwalked path? lol
